The' invention relates to railway frei'ght fears, and moreparti'cu'larly'to dump ears havin I a hopper on ea'ch' s'icle of the'ceriter doors arranged for simultaneous"openingor 'elosingof the'doors.

G and:- :7= show th'e relation. of the ii the.mr

'The' door comprises a main portion 2 formed into wdownwardly projectingbulge preferably having its greatest depth; adjacent the lower margin ofthe door, with the surface'of the bulge between the place of maximumdepth and "the-lower margin of th'e 'elo'o'r inclined ydownwardly so asto discharge the lading immediately upon release of the door. The mainportion merges di rectly into an upwardly projecting flange 3 at certainof the edges of'th'e door. These upwardly projecting flanges arepreferablyf-po'sitioned at the lower and sidemargins of "the'door, butif desired, this fiange'may be continued around the entire perimeterofthedoor. This fl'ange overlaps a portion of the hopper 4 of the car,as shownin Figs. 6 and 7, and forms a seal to restrict the e'c'a'peofthe lading.

This flangemay be reinforced by the re fiange6 which preferablpreje'ct-s outwardly fromthe-door and'the hopper is preferably provided*with an outwardly proj ecting rib 7 set back from the edges of thehopper dooropening which forms a rabbet for-the reception of the fiangeand refiange on the "door. Furthermore,'thi s rib 7 on the hop- =per4-stifl ens t-heedge ofthe door opening and prevents it from beingdeformed.

Agreat many cars now inservice have a hopper on each side of the centersills, each provided with an opening, which open ings are-simultaneouslyclosed by a pair of 'doors connected by a spreader. In-my'const'r'uction I prefer tofa'tta'c'h' the spreader 9' to the door at'its pointof greatest depth, as shown in Figs. 2" and 5. This spreader ispreferably riveted to the main portion, as shown in Fig. 2, or thedoormay be provided with a rib 10 to which the spreader may be secured,-asshown in Fig. 5. The spreader -9-may be secured to both the main portionand the rib, also shown in Fig. 5. --A flat areall ispreferablypro'vided to furnish'a' bearing forthe spreader to keep it from rocking.I V

The-hinge lugs 12 are "preferably cast integral *wi-th the door, whichin the form il- Lustrated', engage hinge butts 13 attached to the' orossrid'ge -14 of the ear. The'up'per edge of the door may be provided witha flange 15 positioned under the ridge 14;.

The accompanying drawings illustrate the preferred form of theinvention, though it is to be understood that the invention is notlimited to the exact details of construction shown and described, as itis obvious that various modifications thereof within the scope of theclaims will occur to persons skilled in the art.
